The Rain Gauge Station - Model 3424 generates real-time data to help in flood warning, reservoir management, and any other application that calls for timely rainfall information. The Rain Gauge Station's data provides information of precipitation patterns and events as they happen, helping the system operator understand and predict runoff. The Rain Gauge Station's information facilitates the decision making of emergency management personnel during times of potential flooding helping to save property and lives.

The Rain Gauge Station's Rain Gauge tipping bucket is machined from a solid piece of aluminum. This eliminates the possibility of cracks forming due to repeated freezing and melting which could result in leakage and errors. The Rain Gauge Station's standard tipping bucket measures 1 mm with each tip of the bucket. An optional 0.01 inch tipping bucket is available for your Rain Gauge Station.

With each tip of the bucket a magnet passes over a sealed reed switch. This switch closure increments one count in an accumulator (counter) circuit in the Rain Gauge Station's Transmitter. This awakens the transmitter and initiates a radio transmission to the Rain Gauge Station's base station consisting of the assigned sensor ID# and the accumulator value. As a result, the computer and its forecasting software computes within 1 mm the rainfall amounts at Rain Gauge Stations throughout the system.

When the tipping bucket top section is mounted on top of the Rain Gauge Station standpipe, the rain gauge funnel opening is 10 ft (3 m) above the ground.

For remote, hard to reach sites, an optional Radio Path Study can be made to analyze radio transmission paths, ensuring clean, accurate signals between various Rain Gauge Station locations.

The Rain Gauge Station - Model 3424 includes a weatherproof Standpipe Assembly, Data Transmitter w/battery, Rain Gauge Top Section, Antenna, and Antenna Mast & Cable.
